Robert Vermeire, author of 'Cocktails, How to Mix Them' took an essential part in the European Golden Age of the 1920's and was the greatest Belgian bartender. US magazine Imbibe even called him one of the 25 Most Influential Cocktail Personalities of the Past Century, alongside such giants as Harry Craddock, David Embury or Dale DeGroff. Yet very little is known about his life. Through extensive research, I have been able to find many pieces of the puzzle, but essential data is still lacking. If you have any information, I need your help!
